1. A fixing device for a circuit board, configured to fix a circuit board onto a component to be fixed and comprising:
a holding portion, configured to hold the circuit board, wherein the holding portion comprises a containing space and a top portion, the top portion comprises an opening allowing the circuit board to pass through the opening to be inserted in the containing space;
a fixing portion, wherein the fixing portion is connected with the bottom portion of the holding portion, and the fixing portion is configured to fix onto the component to be fixed,
wherein the fixing portion is detachably fixed onto the component to be fixed, the fixing portion comprises: a insertion head, configured to adapt to a mounting hole in the component to be fixed, wherein the insertion head can be inserted in the mounting hole; and a neck portion connecting the insertion head and the bottom portion of the holding portion, wherein after the insertion head is inserted in the mounting hole, an outer circumferential surface of the neck portion is rightly opposite to an inner surface of the mounting hole,
wherein a section shape of the mounting hole cut by a plane parallel to the top portion is a first quadrangle, a section shape of the insertion head cut by the plane parallel to the top portion is a second quadrangle, a length of the first quadrangle is larger than that of the second quadrangle, a width of the first quadrangle is larger than that of the second quadrangle, and the width of the first quadrangle is smaller than the length of the second quadrangle, and after the insertion head is inserted in the mounting hole and is rotated by an angle more than 0° and less than 180°, the insertion head and the mounting hole form a crossed structure.
